taberhsmith; What are you trying to do. Have the Alarm trigger the EZIOs inputs or have the EZIO triger the alarms motion sensor input?
Almost sound like you are tying an input to an input.
Anyway the 1.2K resistor is in series with the opto isolators input doide. The voltage drop across the diode and resistor makes the motion input look open to the alarm.
More deatils on your exact needs maybe a help.
